CHAIR-TIP.

Patented May 17, 1921.

7 Application filed April 6,1920. Serial No. 371,602.

new and useful Improvements in Chair- Tips, of which the following is aspecification.

This invention relates to an attachment for furniture and moreparticularly to a device that may be attached to those parts offurniture coming in contact with the floor,

and has for'its primary object the 'provi-,

sion of a simple, inexpensive article that may be readily driven intothe furniture and when in place is very difficult to remove owing to theconstruction of those parts forced into the wood.

An object of the invention is to provide an article that will engage thewood in a more effective manner than similar devices now on the market.

A feature of the invention is the novel manner of forming the prongs sothat a very effective grip can be accomplished between the article andthe wood so that in case the article is forced into wood in a greenstate, the device will'not lose itseffective grip withthe wood when thelatter dries after being used for a certain length of time. 7

With these and other objects in view the invention will be betterunderstood from the following detail description taken in connection'with the accompanying drawings, wherein: V

Figure 1 is aside elevation of the article. Fig. 2 is a transversesectional view. Fig. 3 isa detail view of a portion thereof. Thebodyportion l-of the article is of con cave-convex shape so as towithstand great pressure and to reduce the amount of surface in contactwith the floor. The edge portion of the body is constructed toprovidespear shaped prongs 2 and sharp penetrating edges 3 betweenthe pron s asclearly shown in the sectional view. s far as I have proceeded it willbe, seen that when the prongs will be deeply inserted in the wood andthe penetrating edges 3 will also be driven into the wood foreffectively securing the article'to the furniture and reducing thestrain to which the prongs are subjected due to the fact that theengagement between the cutting edges and the wood will relieve theprongs of a certain amount of lateral strain. The inner surface of eachprong is provided with serrations 4 which also adds materially to theeffective grip of the prongs with the wood.

From-the foregoing description taken in connection with the accompanyingdrawings it should be apparent that I provide a device of simplesubstantial construction in which the penetrating portions are soconstructed and arranged that a more effective grip will be accomplishedbetween the article and the furniture, which isof great advantage whentaken into consideration thatthe wood of some furniture is notthoroughly seasoned before it is put upon the market 1 and thereforemetallic articles forced into the wood quite often become loosened assoon as the wood becomes properly seasoned. Th s defect is overcome inmy device by so shaping the prongs that a locking action is broughtabout between the prongs and the fibers of the wood.

1. An attachment for furniture legs comprising a metallic concave convexbody of substantially circular form having its edges formed with aplurality of equally spaced parallel spear shaped prongs havingsharpened ends, the inner faces ofall'the prongs being formed with aplurality of transverse ratchet shaped barbs.

2. An attachment for furniture legs com prising a'substantially circularconcave c011- vex metallic body having its edge formed with a series ofspaced spearshaped penetrating prongs, the edge of the body between theprongs being cut away parallel with the prongs whereby to define anupper sharp penetrating edge.

In testimony whereof I afiix mvsignature.
